reclaimed by drainage, this should be done even at public expense ; 

 otherwise stock must be fenced out from them. Sources of the 

 watershed, that are infested by the plant should be cleared of it, 

 or the land through which the water flows, must be cultivated. 

 Fodders harvested from infested lands, must be consumed on 

 them, and not carried elsewhere to spread the disease. Above 

 all no seeds of grasses or other plants grown on infested lands 

 should be offered for sale, for use outside such areas. 



In New Zealand where the wide infested ranges are the des- 

 pair of the sanitarian, attempts have been made to reduce the 

 losses by overstocking the land with sheep in early spring and at 

 intervals thereafter, that the young fresh stems of Senecio may 

 be eaten down close and the formation of seed prevented ; also 

 by pasturing such infested lands by two flocks of sheep alter- 

 nately, each being allowed to occupy the ground for six weeks at 

 a time, and then turned for the same length of time into a whole- 

 some pasture. But it is found that in either case, after a year 

 the sheep have cirrhosis and begin to suffer and die, and, it may 

 be added, the frequent shifting from the infested to the sound 

 pastures, is the means of carrying the seeds to the latter and thus 

 extending the area of "the disease. To obviate this the sound 

 pastures should be cultivated in the following year to destroy the 

 young plants as they grow from the seeds. 



This is a matter of immense importance to the future live stock 

 industry, and will warrant rigid government control for the eradi- 

 cation of the pest, but not the common resort of maintaining an 

 expensive sanitary (?), staff engaged in work that can never put 

 an end to the evil. 



CIRRHOSIS IN THE DOG. 



In the dog, cirrhosis, is much more common than in the larger 

 animals, in connection with idle pampered habits, the frequency 

 of diseased heart and consequent disturbance of the circulation, 

 and the presence of parasites in the liver or biliary ducts. Bac- 

 teria intoxication and infection are also common. 



Lesions. The liver is at first tumefied, with hard consistency 

 and rounded edges, and a deep brownish red color, but this is
